The little things matter.
What did you read today? What did you write today?
What did you see as you were travelling? What did you listen to?
What conversations did you have?
Keep a notebook, write these things down. Electronic or pen and paper. Your choice.
Record and use.
Creativity is always with you.
You just need to recognise it and remember it.
Which reminds me, I just need to go and write something down . . .
